Case-back saver

[Waggy]

Was just looking through some posts and saw a watch case back with a paper sticker on it, and also another post there someone was having issues getting the case back off. putting these together in my mind  I had the idea of applying a paper or plastic label to the back of a problem case back to reduce the damage should the attempts to open it cause scratches - basically cheap insurance, was looking at either of the following :

Plastic version:

Paper versions

Thinking plastic may be easier to remove than the paper once the back is off?

Thoughts?
